Tuthill offers the Heavy Duty (HD) Series pumps designed to meet the most demanding industrial applications. These pumps are ideal for handling:

• Slurries

• High viscosity products

• Suspended solids

• Concentrated acids and chemicals

• High temperature liquids

• Sludge, resins, and sewage

• Paints, polymers, plastics, pharmaceuticals, foods

• Shear-sensitive fluids

The HD Series rotary positive displacement, circumferential piston pumps are engineered for severe-duty operations. Their robust construction ensures longer service life even in the toughest environments.

Innovative Design Advantages:

• External Bearing Support: Positioned on both sides of the impellers, providing enhanced stability and allowing the pump to manage high pressures and sudden pressure spikes.

• Rigid HD Design: Prevents shaft deflections that can lead to galling and seizing, outperforming cantilevered designs under load.
